Application filed April 13, 1912. Seria1iNo. .690,625.

This invention relates to air motors of that type designed to be operated' by the constantly moving current of air passing through an upwardly extendmg flue. The invention 1s more particularly animprovement upon the structure disclosed .in Patent No. 7 58,226, issued .torne on April.

26, 1904:, and its principal object is to provide means whereby mounted'for rotation at the outlet end ofthe flue, is protected from rain and snow withopt interfering with the proper circulation o a1r.

A further object is to provide an improved housing for a portion of the apparatus whereby said portion is protected.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :-Figure 1 is. a view partly in side elevation and partly in section of the apparatus having the present improvements combined therewith. Fig. 2 is an end elevation.

Referring to the figures by characters of reference 1 designates a casing having an air chamber therein provided with a series of inlet openings, one of which has been indicated at 2 in Fig. 1. A shield 3 is mounted in front of and spaced from each of the openings 2 so as to prevent the direct passage of air into the casing 1 through the opening.

An upwardly extending air shaft 4 is 1ocated at any suitable distance from the easing 1 and is connected thereto by a conduit or flue 5 the inlet end of which is preferably fiared, as shown at 6 while its outlet end is curved upwardly and opens into the Specification of Letters latent.

bottom portion ofthe air shaft, assliownrat,

[7. An intermediateportion of the flue 5 is oifsetasshown at 8, and mounted for operation'within the flue 5 betweensaid offset portion and the air shaftt is a rotor .9 the shaft 10, of which projects beyond the flue;

5 .andmaybe. provided with-a pulley 11 lwherebymotion' may be transmitted to-the mechanism to be actuated. I A valve, I indicated generally at-.12, .is mounted in the flue 5, preferably adjacent the casing 1 and by meansgthereof the ,cir-

culation or air through; theflue 5'may be controlled. I

A head 18 is mounted for rotation on the upper-end of the air shaft 4: and carries a hood 14 which= overhangs the outlet end of the*air shaft and servesito direct air radially from the shaft. This hood carries a vane 15 which is so located that the open side of the hood 14 is constantly held in position.

to discharge the air current from the air shaft 4 in the direction in which the outer air current is moving.

Arms '16 are secured to the upper end portion of the shaftandare" curved outwardly an'd upwardly therefrom, the said arms being crossedabove the center of the hood and suitably connected so as thus to form a frame for the support of a dome like shield 17. This shield is so proportioned as to fully protect the hood 14' from rain and snow and it will be apparent, therefore, that there is no danger of the hood being held against rotation by ice which would otherwise form thereon in cold'weather.

' Rails 18 are extended upwardly to the upground or other surface on which the apparatus is mounted and these rails are connected by ladder rungs 19. Thus it will be seen that a person can ascend readily to the hood 14.- for the purpose of repairing or cleaning the same.

The flue 5 is preferably inclosed in a h'ousing made up of side walls 20 supporting top sections 21. These top sections are preferably removable so that access may be had conveniently to the flue 5.

It is to be understood that the air shaft 4: will be of any height desired. Obviously the higher the air shaft the stronger will be the currentof airp-assing therethrough. This is due to the factthat warm air naturally rises. The circulation of air through the apparatus is also produced to an increased extent when the. wind is blowing as the external air current thus sets up a suction through the hood 14. As the air passes from casing l and through the conduit 5 to the air shaft I 4:, it moves against and actuates the .rotor 9 so that the rotating pulley 11 can be utilized .for transmitting motion to any mechanism which it may be desired to actuate.

By providing a shield 17 of the peculiar.

shape shown anddescribed, it will be seen that it will prevent downwardly moving currents of airfrom pushingback the air ourrents rising through the air shaft 45. Furthermore, when air currents are moving upwardly or horizontally under the shleld' l7,

7 portions of them will strike the inner surface 7 ofthe shield and thus whirl around under iii-g, an upwardly extending air shaft, a flue 7 connect ng the casing with the lower portion of the shaft, a rotor within the flue, of arms fixedly connected to the air shaft and extending upwardly therefrom, an imperforate semi-spherical dome-like shield supported by the arms and over the air shaft, a hood mounted for rotation upon the upper end of the air shaft andbelow the shield, and a vane carried by the hood and located under and projecting into the semi-spherical shield and in the path of a direct currentof air passing between the air shaft and the shield, to hold the outlet of the hood out of the wind, said shield constituting means for creating a whirling action of a portion 'of the air current passing under the shield.

In testimony that I claim the foregoing as my own, I have hereto ailixed my signature in th'epresence of two witnesses.
